SYRlNGE-NOZZLE.

SPECIFIGATION forming part of Letters Patent No. 7 38,603, datedSeptember 8, 1903. i Application filed T anuary 13, 1902. Serial No.89.440. (No model.)

To all whom it may oonoern:

Be it known that I, HAYDN BROWN, a subject of the King of Great Britain,residing at 44 Hamilton Gardens, St. J ohfs Wood, London, England, haveinvented a new and useful Improvement in Syringe-Nozzles, of which thefollowing is a specification.

My invention relates to an improvement in a\ syringe.- nozzles, and isintended to be attached to the tubing of enema-syringes, siphon vessels,or douche-cans to be passed into the vagina for surgical or hygienicpurposes, fluid being driven through it into the vagina. I attain theseobjects by the meohanism illustrated in the accompanying drawings,inwhichI represent a section of the syringe-nozzle with a slit oropening in the bulb. 3 Figure l is a longitudinal section of thevaginal-tube, and Fig. 2 is a section on line A B of Fig. 1.

Letters refer to parts throughout the views.

In the figures the bore b is made to terminate in a circle at `k at ornot far from the center of the bulb a, and this is met by a slit oropening n, beginning at or near the extreme end m of the bulb, whichsaid slit or opening is continned until it outs into the termination ofthe circular end of the bore.

Thus a slit eects an oxpansion of boreequiv alent to the circularenlargement of the bore, but having the advantage of spreading a fluidwhich is project'ed through the slit and further preventing particlesfrom returning back into the appliance in a return flow through theslit. The narrow slit will prevent certain pieces of debris from beingwashed back and yet permit free flow forward.

The nozzle is an enlarged bulb a and a neck o at the end of the shaft bWith the bore.

What I claim as my invention, and desire to secure by Letters Patent,is-

In a syringe-nozzle, the conbination of an enlarged spherical bulb, ashaft connected therewith provided with a bore terminating in asemispherical end at or near the center of the bulb, and the said bulbbeing provided with a slit beginning at the extreme end thereof andcontinuing toward' the opposite end until it meets the bore of the shaftat the
